The reason I gave it only four stars is because I had a problem, setting it up and finding out what I needed to do. At hand and destruction manual in it would’ve made it very simple. ### 1/5 — Stop working after a 7days *2026-03-20, version 1.0.140* Purchased this mug on Amazon for my husband. It worked for 7 days and went totally dead. Tried to upload the app and it looked as if it was a virus on my phone. The app started blinking continuously. Very disappointing. Now I have to return it. ### 1/5 — A big disappointment *2026-03-03, version 1.0.140* I set the app for 150°, and it automatically drops to 143°. The mug itself started vibrating on its own, and the temperature lights on the mug were flashing. I turned the mug off and turned it back on. That stopped it for a while, but it came back. I am returning this item. ### 1/5 — Firmware issues *2026-01-16, version 1.0.139* Cup stops working after firmware update. Heat turns off on its own. Even though update said it fixes this problem. ### 1/5 — Poor user experience *2025-12-07, version 1.0.139* I know this is half the price of the Ember mug, but ultimately you get what you pay for. There are several issues with this product. Number one, the app user experience is extremely poor. It constantly disconnects from your mug, which means you have to re-pair the mug with your app every single time. There’s no user manual in the app, so I don’t even know how to pair it sometimes; it’s hit or miss. I think you just press the button for two seconds or something, but the Bluetooth connection is very inconsistent. Number two, the battery lasts less than two hours at 145°F - more like 1.5 hours, so you’re only getting about 30 more minutes compared to the Ember mug. Additionally, the app doesn’t allow you to preset the temperature; every time you close the app, it defaults back to the manufacturer’s preset. The charger plate is quite big compared to the Ember mug too - kind of bulky. I will be returning this mug. I am very disappointed. Yes, it is half the price of the Ember mug, but I would gladly pay more for a more premium feel, a better app, and a more consistent user experience. The frustration with this mug and the app is not worth saving $50. ### 1/5 — Useless *2025-10-26, version 1.0.136* App never send Captcha to email. Absolutely worthless with an unnecessarily complicated login that doesn’t even work . It’s a coffee cup, not a bank vault. ### 1/5 — App bugging out for the uv smart water bottle *2025-07-28, version 1.0.131* The bottle serves its purpose but the app or idk I’m stuck in a loop of update 1.2.5 update success, update fail update success then fail. Very irritating can’t force stop the update, drains the battery. ### 1/5 — Not pairing *2025-04-20, version 1.0.126* Love the bottle but the app is not pairing. Have tired everything and still not pairing. ### 1/5 — Unable to connect. *2025-04-09, version 1.0.126* Since the latest update, I can’t connect to my cup. I keep adding the device and it says it’s successful, but it’s not showing up in the app. So now i can adjust the temperature to keep it warm. Useless.
